Zigzag Air Classifier/Sorter
Walle industry Zigzag Air Classifier is an advanced material separation device that utilizes airflow and gravity to efficiently sort lightweight and heavy materials based on density, size, and aerodynamic properties. Widely used in recycling plants, waste processing facilities, and mining operations, it excels at separating mixed waste streams (e.g., plastics, paper, metals, and organics) into high-purity fractions.
Key Features
-
Zigzag Channel Design
- Multi-stage zigzag airflow channels create turbulent and laminar flow zones for precise material stratification.
- Adjustable airflow velocity (5-25 m/s) and angle to optimize separation for different materials.
-
Density-Based Sorting
- Lightweight materials (e.g., films, paper) are lifted by airflow to the upper outlet.
- Heavy materials (e.g., metals, stones) fall through the zigzag path to the lower collection zone.
-
Automated Control
- PLC system with touchscreen interface for real-time adjustment of airflow, vibration, and feed rate.
- Integrated sensors monitor material flow and purity for consistent performance.
-
Modular & Scalable
- Compact design with modular components for easy integration into existing production lines.
- Throughput capacities from 1-20 tons/hour, customizable for small or large-scale operations.
Technical Specifications
- Input Material: Mixed waste, plastics (PET, PE, PP), paper, metals, organics, etc.
- Separation Efficiency: Up to 95% purity for target fractions.
- Airflow System: High-pressure fan (7.5-30 kW) with dust filtration.
- Dimensions: 3-10 m (length) × 1.5-3 m (height), depending on model.
- Power Supply: 380-480V, 50/60 Hz.
Applications
- Plastic Recycling: Separates films, rigid plastics, and contaminants from mixed streams.
- Waste-to-Energy: Isolate combustibles (e.g., paper, wood) from non-combustibles (e.g., metals, glass).
- Mining & Aggregates: Classifies minerals, sand, or gravel by particle size and density.
- Organics Processing: Removes inert materials (stones, glass) from compost or biomass.
Advantages
- High Precision: Achieves fine separation of materials with minimal cross-contamination.
- Low Energy Consumption: Optimized airflow design reduces power usage by 20-30% vs. traditional systems.
- Low Maintenance: Wear-resistant construction with quick-access panels for cleaning and repairs.
- Eco-Friendly: Reduces landfill waste and enhances material recovery rates.
Maintenance Tips
- Regularly clean airflow ducts and filters to prevent blockages.
- Inspect fan blades and vibration motors for wear every 500 operating hours.
- Calibrate sensors and airflow settings quarterly for consistent performance.
